Question on ECC RAM

[Magnet]

Good day,

Curious if this is all expected. A lot of the documentation was for older memory, so that could explain. I'm curious why my memory shows the following output.

System:

• Dell Precision 3460 SFF
• i9-13900 CPU
• W680 Chipset
• Micron MTC20C2085S1TC48BA1R 2x32GB ECC
• Windows 11 Pro

I was trying to validate that the ECC is reporting and working correctly.

Single bit vs multi bit ECC?

64 80
64 80

Why is it not 72 for total?

Is this unique to the RAM/System I'm using, or is this typical DDR5 output?

DDR5 is 2x 32 bit + ECC
2* (32+8) = 80
